Skydiving Speed Test: Recreating Action Film Stunts

Julian Dagen, a world parachuting champion, oversees a skydiving stunt with Vassal and Benoit. They aim to measure the speed of free fall from 4000 meters, adopting different positions to see how it affects speed. Julian curls into a ball, Benoit dives headfirst like a rocket, and Vassal stabilizes horizontally. They achieve speeds of 183, 288, and 325 km/h respectively. The experiment shows that body position, not mass, influences fall speed. Vassal successfully completes his first skydive, proving the hypothesis.

What was the main objective of Vassal's skydiving challenge?

• To measure the speed of a falling body

• To perform a stunt from a movie

• To test new parachuting equipment

• To break a world record

Which position did Julian choose for his jump?

• Feet first

• Head first like a rocket

• Horizontal spread

• Curled up into a ball

What is the purpose of tightening the straps during the jump preparation?

• To ensure safety and security

• To improve visibility

• To increase speed

• To reduce air resistance

What was the average speed reached by Vassal and Julian during their tandem jump?

• 150 km/h

• 183 km/h

• 250 km/h

• 200 km/h

How does body position affect the speed of a skydiver?

• It has no effect

• It significantly influences the speed

• It only affects the speed slightly

• It only affects the speed if the diver is heavy

What was the maximum speed achieved by Benoit in a rocket position?

• 183 km/h

• 325 km/h

• 288 km/h

• 400 km/h

What factor becomes as important as body mass and gravity during the fall?

• Wind direction

• Air resistance

• Parachute quality

• Altitude
